摘要
Abstract
A kind of supercapacitor anode material is introduced.A Polyoxometalate-based coordination polymers(POMCP1)was successfully synthesized by a simple one-step hydrothermal method,and its supercapacitor performance was tested by a three-electrode system.When the current density is 8 A·g-1,the specific capacitance reaches 186.3 F·g-1.When the current density is 30 A·g-1,the specific capacitance remains at 123.9 F·g-1.Combining POMCP1 with Ti3C2Tx,an MXene material with excellent electrical conductivity,the resulting hybrid material,called POMCP1@Ti3C2Tx.POMCP1@Ti3C2Tx,exhibits excellent specific capacitance.When the current density is 8 A·g-1,the specific capacitance reaches 521.7 F·g-1.When the current density is 30 A·g-1,the specific capacitance is still maintained at 402.8 F·g-1,showing excellent rate performance,which exceeds many other materials,provides an effective way to develop hybrid electrode materials based on polyacid-based coordination polymers as supercapacitors.关键词
